The values of water temperature, water flow and mineral temperature were recorded at the inlet and outlet of the cylindrical cooler. Experiments were carried out with five values of the mass flow, keeping the cylinder revolutions constant. The calculation procedure for the system was obtained, in the mineral coolers the heat transfer by conduction, convection and evaporation predominates as a function of the cooling zone. A reduction in temperature is shown with increasing length, the lowest temperature values were obtained for a mass flow of 8 kg/s. The mineral outlet temperature should not exceed 200 oC, therefore it is recommended to work with the mass flow less than 10 kg/s that guarantees the cooling process.</jats:p></jats:abstract><publication_date media_type="online"><month>12</month><day>28</day><year>2021</year></publication_date><publication_date media_type="print"><month>12</month><day>28</day><year>2021</year></publication_date><pages><first_page>254</first_page><last_page>259</last_page></pages><publisher_item><item_number item_number_type="article_number">29</item_number></publisher_item><ai:program xmlns:ai="http://www.crossref.org/AccessIndicators.xsd" name="AccessIndicators"><ai:free_to_read start_date="2021-12-28"/><ai:license_ref applies_to="am" start_date="2021-12-28">https://www.naun.org/main/NAUN/mechanics/2021/a582003-029(2021).pdf</ai:license_ref></ai:program><archive_locations><archive name="Portico"/></archive_locations><doi_data><doi>10.46300/9104.2021.15.29</doi><resource>https://www.naun.org/main/NAUN/mechanics/2021/a582003-029(2021).pdf</resource></doi_data><citation_list><citation key="ref0"><unstructured_citation>Gongora, E. et al (2007).
